This is a little old, but:
[quote]DreamHost is currently connected to the Internet via 8 redundant Gigabit Ethernet (1000Mbps) connections to different carriers to ensure continued network connectivity in case any one (or more) carrier(s) goes down. As of April, 2006, we have connections to Level3, Global Crossing, and Internap.
We also keep our bandwidth unsaturated. We have plenty of extra capacity, with the option to quickly add more bandwidth or additional carriers. We use Cisco switches and routers, as well as Extreme switches, and keep spare hardware on hand in the event of hardware failure. [/quote]
Speeds are generally “good” or better; however, if you search this forum, you’ll find some complaints. There are too many things that impact speeds, from user’s ISP connections to server software, including your site, to give simple answers.
